Analysis And Optimal Configuration Of Integrated Community Energy System Oriented To Demand Response

Our country is short of energy resources,the waste of energy is day by day serious,environmental problems are increasingly serious in the process of economic development.The integrated community energy system is to solve these problems.the demand side response has prominent peak regulation potential,this paper studies the integrated community energy system considering demand response.On the premise of meeting the energy needs of users,it analyzes the energy equipments of the current typical integrated community energy system in detail,and optimizes the equipment capacity and operation scheduling with the objective of economic optimization.Firstly,the typical integrated community energy system structure model is analyzed in detail,the working principle of each equipment is explained,and the mathematical model of each equipment suitable for the optimal configuration of the system is established.Then from the aspects of the use and economic efficiency of energy consumption in our country,combining with the time sharing price and the natural gas price,the energy consumption economics are compared in detail.Finally,a typical integrated community energy system structure is proposed,which includes gas turbines、waste heat boilers、solid electric regenerative boilers、absorption refrigerating machines、electric refrigerating machines and other energy conversion equipment and energy storage equipment.Finally,considering the impact of demand response regulation on the optimal configuration of the system,an optimal scheduling model with the lowest total cost of the system is established,focusing on economic optimization.A two-layer optimization model based on CPLEX solver is proposed.The internal and external optimization results cooperate with each other,and the optimal scheduling results can be obtained while solving the equipment capacity configuration.Taking a comprehensive park in Beijing area as an example,the results are verified by MATLAB tool,which proves that the two-layer optimization model proposed in this paper can indeed improve the economy of the integrated community energy system,reduce the total operating cost of the system,and give full play to the potential of comprehensive demand response.
